Motion Detection Sensitivity

There is no clear cut answer to sensitivity settings that can truly eliminate false positives, while maintaining that they trigger as desired, for all cases. The problem is simply that everyone's cameras will be looking at such drastically different scenes, that one person can have false positives on a very low sensitivity (due to snow) whereas the other can use the same settings and not even catch the movements of trees in the wind.

The best thing you can do is work out a configuration for each camera based specifically on what your cameras are likely to register as motion and customize your settings to your preference.
